From the Guidelines
Isotretinoin may be appropriate therapy for an 18-year-old male with nodulocystic acne who has stable ulcerative colitis on mesalazine, but requires careful consideration and monitoring. The decision should involve both a dermatologist and gastroenterologist working together. While there have been concerns about a potential link between isotretinoin and inflammatory bowel disease, the evidence is inconclusive, and patients with pre-existing stable ulcerative colitis can often safely use isotretinoin 1.
Key Considerations
- The standard isotretinoin regimen would be 0.5-1 mg/kg/day divided into two doses for 15-20 weeks, with a cumulative dose goal of 120-150 mg/kg 1.
- Before starting treatment, baseline laboratory tests including liver function, lipid profile, and complete blood count should be obtained, with monthly monitoring thereafter 1.
- The patient must be enrolled in the iPLEDGE program for pregnancy prevention, though this is less complex for males 1.
- Regular gastroenterology follow-up is essential during treatment to monitor for any worsening of ulcerative colitis symptoms 1.
- If colitis symptoms worsen, isotretinoin may need to be discontinued 1.
- Alternative treatments like topical retinoids, antibiotics, or benzoyl peroxide combinations could be considered if isotretinoin is deemed too risky, but these are typically less effective for severe nodulocystic acne 1.
Recent Guidelines
The most recent guidelines from 2024 support the use of isotretinoin for severe recalcitrant nodular acne vulgaris, with a recommended cumulative dose of 120-150 mg/kg 1. However, the guidelines also emphasize the importance of careful consideration and monitoring in patients with pre-existing conditions, such as ulcerative colitis.
Monitoring and Follow-up
Regular monitoring of liver function tests, serum cholesterol, and triglycerides at baseline and again until response to treatment is established is recommended 1. Additionally, patients should be monitored for any indication of inflammatory bowel disease and depressive symptoms, and educated about the potential risks with isotretinoin 1.

From the Research
Considerations for Isotretinoin Therapy
- The patient in question is an 18-year-old male with nodulocystic acne and stable ulcerative colitis on mesalazine, considering isotretinoin therapy.
- A case report from 2 describes a patient who developed ulcerative colitis after using isotretinoin for acne treatment, suggesting a possible correlation between isotretinoin use and ulcerative colitis.
- However, this correlation is not extensively studied, and more research is needed to fully understand the relationship between isotretinoin and ulcerative colitis.
Alternative Treatment Options
- A case study from 3 reports a patient with ulcerative colitis who developed acne fulminans, which was successfully treated with prednisolone and diaminodiphenylsulfone.
- Another study from 4 describes a patient who developed neutrophilic dermatosis after treatment with doxycycline and isotretinoin for acne conglobata.
- These cases suggest that alternative treatments may be effective for patients with acne and ulcerative colitis.
Isotretinoin Dosage and Efficacy
- A study from 5 found that low-dose isotretinoin (0.2-0.4 mg/kg/day) was effective for patients with moderate inflammatory acne, with fewer side effects and lower costs compared to traditional dosing.
- A review from 6 discusses the management of acne vulgaris, including the use of isotretinoin for severe recalcitrant nodular acne, and notes that it is often used to treat resistant or persistent moderate to severe acne.
Decision Considerations
- When considering isotretinoin therapy for the patient, it is essential to weigh the potential benefits against the potential risks, including the possible correlation with ulcerative colitis.
- The patient's stable ulcerative colitis on mesalazine and the severity of their nodulocystic acne should be taken into account when making a decision about isotretinoin therapy.
- Close monitoring and regular follow-up appointments may be necessary to ensure the patient's safety and adjust treatment as needed.
